A pneumatic nebulizer that produces a high volume of aerosols for inhalent delivery of medications and other constituencies. High pressure gas formed into a gas jet is passed through a thin choked region of fluid that is entrailed and impinged upon an aerosol amplifier which creates a spray whose aerosol components are directed up through vents to an aerosol outlet for delivery. Larger-sized liquid particles are caused to pool up in a region surrounding the aerosol amplifer and then drip down back into the liquid medication reservoir.

A system and method for generating an oxygen enriched aqueous solution for therapeutic application includes a diffuser comprising a first diffusing member having a surface incorporating surface disturbances, and a second diffusing member positioned relative to the first diffusing member to form a channel through which an aqueous solution and oxygen gas may flow.

A heat and humidity exchanger comprises a pleated membrane cartridge disposed in a housing. The cartridge comprises a pleated water-permeable membrane via which heat and humidity can be transferred between two fluid streams. A flow field element is disposed within some or all of the folds of the pleated membrane, for directing the stream over the inner surfaces of the folds. The flow field path defined by the flow field element enhances flow distribution across one or both membrane surfaces, controlling the relative flow paths of the two streams on opposite sides of the membrane and reducing the pressure drop across the heat and humidity exchanger. The flow field elements provide improved water transfer and allow for a more compact device. The flow field elements can also assist in supporting the pleated membrane and controlling the pleat spacing within the pleated membrane cartridge. The heat and humidity exchanger is particularly suitable for fuel cell and energy recovery ventilator (ERV) applications.

A process and system for producing hydrocarbon compounds or fuels that recycle products of hydrocarbon compound combustion—carbon dioxide or carbon monoxide, or both, and water. The energy for recycling is electricity derived from preferably not fossil based fuels, like from nuclear fuels or from renewable energy. The process comprises electrolysing water, and then using hydrogen to reduce externally supplied carbon dioxide to carbon monoxide, then using so produced carbon monoxide together with any externally supplied carbon monoxide and hydrogen in Fischer-Tropsch reactors, with upstream upgrading to desired specification fuels—for example, gasoline, jet fuel, kerosene, diesel fuel, and others. Energy released in some of these processes is used by other processes. Using adiabatic temperature changes and isothermal pressure changes for gas processing and separation, large amounts of required energy are internally recycled using electric and heat distribution lines. Phase conversion of working fluid is used in heat distribution lines for increased energy efficiency. The resulting use of electric energy is less than 1.4 times the amount of the high heating value of combustion of so produced hydrocarbon compounds when carbon dioxide is converted to carbon monoxide in the invention, and less than 0.84 when carbon monoxide is the source.

When the carbonization / gasification apparatus is used to provide fuel to an electric power generator set, exhaust heat from the generator power plant is fed back to the carbonizer, and can be supplemented by exchange of heat from the gas delivered to generator power plant from the outlet of the gasifier.

A fuel processing system is operable to remove substantially all of the sulfur present in an undiluted hydrocarbon fuel stock supply used to power a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The power plant hydrogen fuel source can be gasoline, diesel fuel, naphtha, light hydrocarbon fuels such as butane, propane, natural gas, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a nickel desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds react with the nickel reactant, and are converted to nickel sulfide while the desulfurized organic remnants continue through the remainder of the fuel processing system. The system does not require the addition of steam or a hydrogen source to the fuel stream prior to the desulfurizing step. The system operates at relatively low temperatures and can be used to desulfurize either a liquid or a gaseous fuel stream.
